On Linux platforms, a text selection is always visible and vanishes the moment a second selection is made. Since the Linux specific behavior can't be added to the generic HidingSelectionTest, those test cases are added along with the original test cases from HidingSelectionTest to the new MultiSelectionTest class.
What is the reason to copy HidingSelectionTest to MultiSelectionTest to 
run it only on Linux? I don't see this as part requested in the TCK red 
issue.

As for selection vanishing only when another text is selected in the 
same window. I'm not sure that this should be the rule. At first not all 
native apps follow that on Linux. And the second, we need to keep 
balance between native behavior and being cross-platform. When the 
behavior is ambiguous for the user we have to follow the native way but 
when there no such issues the behavior should be cross-platform. Anyway, 
in my understanding this topic is out of the scope of the issue you need 
to fix in this bug.

>> Hi Semyon, I ran those tests and found to be passed on the selected platforms. Since in linux platforms, we can’t have multiple selections visible at the same time, I have made a different test MultiSelectionTest along with other test cases as is in the HidingSelectionTest. This test passes on the linux platform and fails on other platforms because of the behaviour change on the linux platform.

>>>>>> Summary: The text selection visibility behaves differently on linux/solaris platforms compared to windows or Mac platforms. There were 2 related fixes that went in this area. There are: https://bugs.openjdk.java.net/browse/JDK-5100950 and https://bugs.openjdk.java.net/browse/JDK-8188081. While fixing the bug 5100950, a mistake was made to clear out the selection data. This behaviour is NOT the native behaviour as found in other native applications. The behaviour always is to retain the selection data and control the visibility of it depending on the conditions. On linux flavours we display only one selection data and upon toggling active application we get to see the selection data of that particular application hence we never loose the data. These behaviour differences are tested via the test components attached with this fix.
>>>>>> Considering the time, this fix addresses only the awt text components like textarea and textfield. Both these classes uses the same caret implementation, hence a change to the XAWTCaret is sufficient to reflect to both the text components. Swing based text components will be addressed later if there are any issues found.
